As hydrogen is expected to play an important role in the global energy system, hydrogen transport present bottlenecks for long-distance hydrogen supply chains (HSCs). One of the potential solutions is the use of liquid organic hydrogen carriers (LOHCs), with methylcyclohexane (MCH) paired with toluene being a state-of-the-art system in industrial applications. LOHCs maintain chemical stability in the liquid phase under ambient conditions and can potentially utilise existing infrastructure, making them more advantageous than other hydrogen carriers. However, LOHC-based HSCs face challenges, particularly in heat supply for the energy-intensive endothermic dehydrogenation process, as well as uncertainties associated with the large-scale maritime transport of toluene/MCH.
